Abstract

La présente invention concerne un compresseur à spirale comprenant un mécanisme de pompage à spirale comportant une spirale orbitale (20) présentant une paroi de spirale orbitale (34) s'étendant axialement depuis une plaque de compresseur orbitale (36) en direction d'une spirale fixe (22) et une spirale fixe présentant une paroi de spirale fixe (28) s'étendant axialement depuis une plaque de spirale fixe (30) en direction de la spirale orbitale. Le compresseur comprend en outre un arbre d'entraînement s'étendant axialement (14) et présentant une partie arbre excentrique (16) de sorte que la rotation de la partie arbre excentrique imprime un mouvement orbital à la spirale orbitale par rapport à la spirale fixe pour pomper le fluide d'une entrée (24) à une sortie (26) du mécanisme de pompage. Une partie d'extrémité axiale d'une des parois de spirale (28, 34) présente un premier agencement d'étanchéité et un second agencement d'étanchéité disposé en série le long de la paroi de spirale de l'entrée à la sortie pour établir une étanchéité entre la partie d'extrémité axiale de la paroi de spirale et la plaque de spirale de la spirale opposée, ledit premier agencement d'étanchéité présentant des premières caractéristiques d'étanchéité sélectionnées selon des exigences d'étanchéité locales par rapport aux premiers agencements d'étanchéité et ledit second agencement d'étanchéité présentant des secondes caractéristiques d'étanchéité sélectionnées selon les exigences d'étanchéité locales par rapport aux seconds agencements d'étanchéité, et lesdites premières caractéristiques d'étanchéité sont différentes desdites secondes caractéristiques d'étanchéité.
